Adjusting Stud Mount Rockers - and checking pushrod length

The other procedure is the one explained at http://www.totalengineairflow.com/tech/valvelash.php .... bring one cylinder to TDC, but adjust the previous cylinder intake valve in the firing order, and the next cylinder exhaust valve in the firing order..... or as shown in their tables for the 351w and 302 based firing orders.



Cylinder at TDC is top row, and the intake and exhaust valves to adjust are the 2nd. and third rows.

When I worked at Lunati back in the before they were Holley (around '90 - in college at the time). There was a guy there named Jim Miller - he and i got along cuz were the only FORD guys in the building. I was told he was a rocker arm guru and he and a whole different idea on how this stuff was supposed to work.  He and Joe Lunati were working on developing their own rockers.  Then one day I came to work and no more Jim Miller. 

Anyway, I was wondering if you the exp. guys have an opinions or comments on his theories/products.    I am smart enough to know i don't know anything about it!

Hi Just a quick tip... similar to TEA's valve lash adjusting procedure.

Firing order:

1372
6548

When both valves of a particular cylinder are 'rocking', adjust both intake and exhaust valves of the opposite cylinder as above. So when 3 is rocking adjust cyl 5 in/ex, and so on.

I believe this way is the quickest when your turning the engine by hand... It works for my afr205, XR292R, 347 stroker.

If you flip the plunger on a Hyd lifter and get the snap ring to lock in, will it still be .020 off? Or because of the snap ring locking in, will it force it down to be in the exact place a fully pumped hyd lifter would be?

you should have to grind .020 off to get it back together.   joe

Added: and to clarify some questions.....
You could also flip the plunger and not grind the .020" off, the snap ring will be a little difficult to install but it will work. If you intend to use the lifter in your build, disassemble it, flip the main plunger to its original position, reinstall the spring and reassemble the lifter. That's how I prepared the 4 lifters I have for degreeing cams, checking valvetrain geometry and PtV.

I can't quite quote properly because I'm on my phone but that was in the second post of the article, I was wondering if you did it that way if you would end up .020 tall.

No, you will never be taller than the Retainer clip on the lifter.

Just to try to help others, and add to this thread.....

Ive heard different about setting the preload. Some have said a 1/4 is all you need, and I've heard that for high rpm's and "high performance" motors, to do a full turn.

what is the standard? or what does different amounts of preload effect?


(great write up guys!!!)

this method works on any engine from what ive done in the past.
